JOSE HOFFAY OF LONDON, ENGLAND.

GRAMOPHONE AND THE LIKE MACHINE.

To all whom it may concern Be it knownthat I, Josn HOFFAY, a citizen ofthe Republic of Mexico, and a resident of London, England, have invented certain new and useful Improvements in Gramophones and the like Machines; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to improvements in or relating to the mounting of sound boxes 1n gramophones, phonographs and the I like machines.

The invention consists in a coupling comprising a hollow block or member, permanently or detachably connectedto the sound box or the tone arm or sound tube and pivoted on .the tone arm or sound tube or ona support thereon, preferably at a point outside the sound passage adapted to present an opening facing forwardly, approximately in the direction of the sound groove, or facing laterally transversely to the sound groove, for connecting the sound 'box to the tone arm or the like, the hollow block or member being adapted, in one position, to

complete a tight communication between the I sound box and the tone armor the like, and, in another position, to break the communication, and displaceable means being provided for restoring the communication when so broken and at such time aiding in secur ing the hollow block or member in position.

The invention is represented, by way of example, in the accompanying drawings, in which Figure 1 is a plan view of my improved device; Fig. 2 is a side elevation thereof, looking in the direction of the arrow 2 shown in Fig. 1; Fig. 3 is a detailseetional view taken on the line 3-3 shown in Fig. 2; Fig. 4 is a plan view of the device shown in Fig. 1; Fig. 5 is a side elevation looking in the direction of the arrow 5 shown in Fig. 4; Fig. 6 is a detail sectional View taken on 'theline 6+6 shown in Fig.5; Fig. 7 is a detail sectional view taken on the line 7-7 shown in Fig. 3; and Fig. 8 is a detail. sectional view taken on the line 88 shown in Fig. 6. v

In carrying out the invention'the coupling may, as shown in Figs. 1 to 6, comprise a block or member, 12, pivotally mounted, at 13, in a casing, 14, on the end ofthe tone arm, 15. The block is formed with above, 16,' extending. therethrough for receiving Specification of Letters Patent.

the hollow boss, 17, of the sound box, 18. The pivot is disposed at one side of the center of the passage through the tone arm so that by turning the. block outward to the position shown in Fig. 3, the bore, 16, is directed laterally for holding the soundbox, 18, approximately in the direction of the sound-groove in the record, 19, ride Fig. 1; and so that by turning the block inward to the position shown in Fig. 6, the bore, 16, is directed forwardly for holding the sound-box transversely to the sound groove, aide Fig. 4..

A complementary hollow elbow-piece,

cover, or equivalent means, 20, is pivotally mounted, at 21, in the casing, '14, at the other side of the tone arm, so that when the block, 12, is in the outward position shown in Fig. 3, bearing against the casing, 14, which serves as a stop, the elbow-piece, 20, may be turned inward as shown to complete the communication between the sound-box and the tone arm and aid in securing the block, 12, rigidly in position, by serving as a rigid obstruction between the casing, 14, and the block, 12. When the block, 12, is in the in: ward position shown in Fig. 6, the elbowpiece s turned outward clear of the other parts. The elbow-piece may be turned outwardwagainst one angularly bent end, serving as a stop, of a piece of spring wire. 22, the other end of which is secured to the casing,14.

The block, 12, and the elbow-piece, 20,

-may be secured in their respective inward positions by detents, 23, on the casing. 14:. The detents, 23, consist of inward projections onth'e-sides of the casing, 1 1, and they operate by engaging in indents, in the sides of the elbow-piece, 20, and in the sides of the block, 12, as shown in Figs. 7 and 8. The detents, 23, being formed on the thin sides of the casing, 14, may be sprung out- E 24; represents a given distance on the sound record, from the vertical axis, 25, of 1 sound box, a tone arm, a

the tone arm, and the heavy dotted line, 26, represents the stylus lever and st lus. It will be seen in Figs. 1 and 4 that tile stylus working position, :0, is the same both for zig-zag and for hill-and-dale records.

The sound box boss may be secured in the block,.12,by a set screw or in any other convenient manner. and it is only necessary to turn the block in the casing, as shown in Fig. 6, and then move the elbow piece out of the way, or at right angles to the casing, as shown in Fig. 3; thereafter-movin the elbow piece to restore communication, t ere-- by adjusting the sound box for playing rec.- ords of difl'erent cuts according to requirements.

27 is the pivot of vertical oscillation of the tone arm.

In the claims, the term tone arm is intended, besides any special si ification-it may have, to comprehend any orm of articulated or non-artlculated sound tube, horn, or other sound conveying means. 7
